Sound absorbing and vibration damping metal strip, molding, and method of producing a sound absorbing and vibration damping metal strip

Abstract

A metal strip, more particularly a metal strip for producing vibration damping moldings, is provided with a layer of adhesive viscoelastic plastics and permits coiling and comprises an anti-adhesive film-type coating. In a method of producing a metal strip, the metal strip is preferably degreased, preferably stretched, possibly pretreated and coated one-sided with an adhesive viscoelastic plastics. In addition, an anti-adhesive film is applied to the metal strip.

What is claimed is:  
     
       1. A metal pad for producing vibration damping moldings, comprising a single metal strip one surface of which is provided with a layer of adhesive viscoelastic plastics for bonding said vibration damping moldings to components exposed to vibration, said metal pad permitting coiling and further comprising an anti-adhesive film coating. 
     
     
       2. The metal pad for producing vibration damping moldings as set forth in  claim 1 , wherein said adhesive plastics layer and said anti-adhesive film are provided on the same side of said single metal strip. 
     
     
       3. The metal pad for producing vibration damping moldings as set forth in  claim 2 , wherein said anti-adhesive film is a cover film. 
     
     
       4. The metal pad for producing vibration damping moldings as set forth in  claim 1 , wherein said adhesive plastics layer and said anti-adhesive film are provided on differing sides of said single metal strip. 
     
     
       5. A metal pad for producing vibration damping moldings, comprising a single metal strip one surface of which is provided with a layer of adhesive viscoelastic plastics for bonding said vibration damping moldings to components exposed to vibration, the metal pad permitting coiling and further comprising an anti-adhesive film coating, wherein said adhesive plastics layer and said anti-adhesive film are provided on differing sides of said single metal strip and wherein said anti-adhesive film is a lacquer film. 
     
     
       6. The metal pad for producing vibration damping moldings as set forth in  claim 1 , wherein said viscoelastic plastics layer is self-adhesive. 
     
     
       7. The metal pad for producing vibration damping moldings as set forth in  claim 1 , wherein said viscoelastic plastics layer is coated with an adhesive. 
     
     
       8. The metal pad for producing vibration damping moldings as set forth in  claim 1 , wherein said viscoelastic plastics layer is a double-sided viscoelastic structured adhesive strip. 
     
     
       9. The metal pad for producing vibration damping moldings as set forth in  claim 1 , wherein said single metal strip is made of aluminum, an aluminum alloy, zinc or steel. 
     
     
       10. The metal pad for producing vibration damping moldings as set forth in  claim 5 , wherein said single metal strip is made of aluminum, an aluminum alloy, zinc or steel. 
     
     
       11. A mounding produced by processing a metal pad as set forth in  claim 1  with molds and/or dies. 
     
     
       12. A molding produced by processing a metal pad as set forth in  claim 5  with molds and/or dies. 
     
     
       13. The metal pad for producing vibration damping moldings as set forth in  claim 3 , wherein said cover film is a film of paper or plastics or a coated aluminum foil or a mixture thereof. 
     
     
       14. The metal pad for producing vibration damping moldings as set forth in  claim 8 , wherein said double-sided viscoelastic structured adhesive strip is a plastics strip provided with a viscoelastic and bonding adhesive on both sides.
